Usage Suggestions:

Crystalline polyester resin, which is characterized by low melt viscosity above the melting point, is currently known to be used in powder coatings to improve coating leveling. It is necessary to pay attention to its characteristics that may cause the preparation and processing of powder coatings to be different from the existing ones. The craft is different. The product is special, other specific applications please explore by yourself. The company does not provide technical services for this product.
